1. megapixels

2. sensor size

The larger the sensor the more light the sensor captures yielding in better image quality.

Polaroid Snap: 81.2 x 25.4mm

23.5 x 15.6mm

3. focus points

The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.

6. maximum light sensitivity

With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.

15. has a stereo microphone

A stereo microphone allows to record audio files or movies in stereo without an external microphone.

16. Has phase detection autofocus for photos

A phase detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images.

19. has built-in optical image stabilization

Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.
